cciss - Smart Array 641 - gentoo linux

Hi,

I'm trying to install a gentoo linux using a Raid 5 on a smart 641, on a ML370R03.

But the installation CD is unable to load the cciss module. (gentoo 1.4 rc4)- I tried with a RH 9.0, the cciss module got up, but then I had another issue with the system that was unable to find the CD on /dev/hda and I wasn't able to got further in the installation.- I tried to compile the module on an other machine, copy it to a floppy, and load it from the console but I had full page of unresolved links.- I don't have any partition on my raid.

Do I need to install my system with a RH8, using the provided drivers and then migrate to the release I need ?Or is there a trick to load a working module on another release ?
